3.1. Description of the tools and reliability General anxiety was measured by a standardised tool State Trait Anxiety Inventory (STAI) (Spielberger, 1989), a self-report 40 item Likert scale with total score of 160 and is widely used in pregnancy (Faisal-Cury & Rossi Menezes, 2007). Both state and trait anxiety were measured and analysed separately. Internal consistency ranges from 0.86 to 0.85 for state and 0.89 to 0.91 for trait subscale. Cronbach’s alpha was 0.88 for state and 0.83 for trait anxieties, reflecting the tool reliability. Pregnancy-specific anxiety was assessed by a standardised structured Pregnancy-Specific Anxiety Inventory (PSAI), 40 items self-report questionnaire on a five-point Likert scale with a maximum score of 200. It measured the intensity of woman’s pregnancy anxiety related to four areas of pregnancy and childbirth. Anxiety about Being Pregnant (ABP) with 16 items; Anxiety of Childbirth (ACB) with 10 items; Anxiety about Breastfeeding (ABF) with eight items and Anxiety about New born Care (ANB) with questions items were parts of the PSAI. The face and content validity of the PSAI were established by expert review and pilot study.
